| In Clifford algebra, you _can_ divide by any nonzero vector.

Absolutely!

But it should be pointed out for the non-cognoscenti that the ordinary
vector dot product is not the vector multiplication that has an inverse
in Clifford Algebras.

Indeed! And I hope (trust) that no one inferred from my post the
contrary.
